How can someone's waist be THAT tiny?!

In a new Instagram photo posted by makeup artist Vincent Oquendo, model Bella Hadid poses in just her underwear — and all commenters can talk about is the 20-year-old's unbelievable proportions, particularly in her midsection.

Vincent shared the pic after news broke that the brunette beauty would be walking in her first Victoria's Secret Fashion Show. "Congrats my little baby bells on getting @victoriassecret! It's been a beautiful ride so far and I can't wait to see what's next!" he wrote.

Bella's older sister Gigi Hadid also confirmed that she'd be modeling in the show for a second year in a row. "There is no feeling in the world like walking down this runway. I'm elated to say I'll be returning to the @VictoriasSecret Fashion Show this year," she captioned a video of her 2015 debut.
